getline不使用fstream输出

Question

这是我的课程和我的课程。我没有得到任何错误，但是，输出文件只显示int值而不是字符串值。我怀疑这可能是因为我要求getline输入，但我无法弄清楚我做错了什么。救命！当输入是“哈利波特”，“好事”时，这是输出的样本，4,1111：

每次获得用户输入时，您都在创建一个新的TVShow。

 while(choice!='4')
    { //new option = what comes back from menu()
        choice=menu();
        TVShow T;
            if(choice!='4')

将TVShow T;移到while循环之外。
